Less than 5 ppm - just like the rain water in my area!!
Love my plants and trying to keep to the watering schedule so far so good. Thanks for your amazingly good service

- All carnivorous plants should be grown using pure, low mineral water. If you do have hard tap water, it is best to use collected rain water, distilled water, reverse osmosis water, or de-ionized water
- Water vendors are starting to pop up in various suburbs across South Africa and when rainwater is scarce these vendors are a good inexpensive source for pure water for your carnivorous friend
- Distilled- and Reverse osmosis water are often sold at most pharmacies, Oasis, Dischem, Builders Warehouse and the pharmacy section of large retail stores such as Checkers Hyper and Pick n Pay
- Note that still and sparkling drinking water sold in the cooldrink section at retail stores are not suitable for carnivorous plants. Bottled water sold under the bottling brands aQuellé, Valpré, H20 to go, Bonaqua and others often have added minerals and is not a suitable replacement for distilled or RO water
- Always read the label. Distilled water sold as 'battery water' may contain sulphuric acid and will kill your plant. Reverse osmosis water typically have a TDS value <20 PPM
- In all cases, a total dissolved solids (TDS) measurement below 100 parts per million (PPM) is recommended for cultivating carnivorous plants
General notes on The Reverse Osmosis system - What is reverse osmosis water?
Reverse osmosis, is the process of osmosis backwards. Osmosis is the passage of water through a protein membrane (like our skin, or the inside of a plant cell) to equalize the concentration of particles dissolved in the water. The protein membrane allows water to pass through, but molecules larger than water (things like minerals, salts, and bacteria) cannot. Water flows back and forth until the concentration is equal on both sides of the membrane, and an equilibrium is formed.
Let’s apply this knowledge to water purification. We want to drink water from a lake or stream, but it contains contaminants like salt, minerals, and bacteria, that make it undrinkable. By applying pressure to water as it passes through a membrane, the water can be forced to move away from the membrane rather than attempting to form an equilibrium like normal. This motion is where the “reverse” comes from. Water is forced through the membrane which blocks an extreme majority of contaminants from coming through.
In water treatment, reverse osmosis can usually remove between 96 and 99% of most contaminants, including salts and minerals, dyes, particles, bacteria, and hazardous metals
General notes on quenching your carnivorous plant's thirst
- Most carnivorous plants may be watered using the tray method
- Simply put your plants in their pots into a tray and fill it with 1cm pure water
- This is really the best and easiest way to make sure your plants don’t ever dry out
- Exceptions are Nepenthes, Cephalotus, mexican butterworts and Drosophyllum - these plants are prone to root rot if kept standing in water for extended periods of time, thus their watering preferences are slightly different in the sense that they need soil only moist to the touch with good drainage, without letting the soil dry out completely
Reverse osmosis water is sold in 330ml and 500ml screw top bottles
5ℓ available on pre-order (due to weight, our 5ℓ bottles are available for collection only)
